Jail cloning

jclone command

% cbsd jclone
% cbsd jrclone

Description:

Creates a clone of a given jail. The command requires the name of the original jail (passed with old) as well as a name for the clone, specified with new and a FQDN (hostname) with host_hostname. Optionally a new IP Address can be given with the ip4_addr parameter (multiple IPs need to be separated by commas).

*** Attention ***: Since 11.0.10 version, CBSD on ZFS-based hosters will be use ZFS clone features!

ZFS clone features is ultra fast operation (thanks to Copy-on-write), but imposes some restrictions - you will be dependent on the parent snapshot. If you try to remove parent environment, CBSD automatically executes the zfs promote command, but when you works with snapshot independently - just keep it in your mind

You can control this behaviour via clone_method= argument or, to set it globally, use rclone.conf and bclone.conf to overwrite settings from 'auto' to 'rsync':
